High Capacity Color Barcode (HCCB) is the name coined by Microsoft for its technology of encoding data in a 2D "barcode" using clusters of colored triangles instead of the square pixels traditionally associated with 2D barcodes or QR codes. Data density is increased by using a palette of 4 or 8 colors for the triangles, although HCCB also permits the use of black and white when necessary. It has been licensed by the ISAN International Agency for use in its International Standard Audiovisual Number standard, and serves as the basis for the Microsoft Tag mobile tagging application .
The technology was created by Gavin Jancke, an engineering director at Microsoft Research. Quoted by BBC News in 2007, he said that HCCB was not intended to replace traditional barcodes. "'It's more of a 'partner' barcode', he said. 'The UPC barcodes will always be there. Ours is more of a niche barcode where you want to put a lot of information in a small space.'"

Famous quotes containing the words high, capacity and/or color:
“Oh may my heart’s truth
Still be sung
On this high hill in a year’s turning.”
—Dylan Thomas (1914–1953)
“He has a capacity for enjoyment so vast that he gives away great chunks to those about him, and never even misses them.... He can take you to a bicycle race and make it raise your hair.”

“‘Twas mercy brought me from my Pagan land,
Taught my benighted soul to understand
That there’s a God, that there’s a Saviour too:
Once I redemption neither sought nor knew.
Some view our sable race with scornful eye,
“Their color is a diabolic die.”
Remember, Christians, Negroes, black as Cain,
May be refin’d, and join th’ angelic train.”
—Phillis Wheatley (c. 1753–1784)
